Method Detail

adaptValueType

public Comparable<?> adaptValueType(Object value)

Description copied from interface: IRangeAdaptor

Adapts value type to the type of specific IRangeAdaptor implementation. To have the possibility to compare these values.

Specified by:

adaptValueType in interface IRangeAdaptor<ARangeIndexEvaluator.IndexNode,Comparable<?>>

Parameters:

value - that is going to be compared with values returned by IRangeAdaptor.getMax(Object) and IRangeAdaptor.getMin(Object) values.

Returns:

value, casted to the type of specific IRangeAdaptor implementation.

getMax

public Comparable<Object> getMax(ARangeIndexEvaluator.IndexNode param)

Description copied from interface: IRangeAdaptor

Gets max value of range.

Specified by:

getMax in interface IRangeAdaptor<ARangeIndexEvaluator.IndexNode,Comparable<?>>

Returns:

the max bound of the expression min <= X && X <= max. Returns null if needs maximum max posible value.

getMin

public Comparable<Object> getMin(ARangeIndexEvaluator.IndexNode param)

Description copied from interface: IRangeAdaptor

Gets min value of range.

Specified by:

getMin in interface IRangeAdaptor<ARangeIndexEvaluator.IndexNode,Comparable<?>>

Returns:

the min bound of the expression min <= X && X <= max. Returns null if needs maximum min posible value.

useOriginalSource

public boolean useOriginalSource()

Specified by:

useOriginalSource in interface IRangeAdaptor<ARangeIndexEvaluator.IndexNode,Comparable<?>>
